Notes on event

At 15.25 hours on 27 June 1942 the unescorted Las Choapas (Master Pedro Calderón Lozano) was hit aft by one torpedo from U-129 and sank in flames north of Tecotutla, Vera Cruz. The survivors in three lifeboats were questioned by the Germans, but the U-boat then had to submerge and leave the area when a Catalina aircraft was spotted.
